I am using this phone from last 2 years. And I am highly satisfied with This mobile. It has a very good configaration like 1gb ram, hd display, 1.3 ghz processor and many more that makes this mobile run very smoothly. Battery life is very good. On an average it can easily make mobile run for one day if used very heavily. call quality is average. Sound speaker are loud and Clear enough to listen songs. Headhpone quality is also above the average. My gaming experiance was good although I am not a very big gamer. I would recommend this phone to everyone who want a reliable phone at the price of rs 20000.
